Oceans: Into the Blue is a documentary that "explores the extraordinary adaptability and ingenuity that enables humans to survive in the marine environment, combined with the profound effect living by the sea has had on our cultures".

In this clip, filmed underwater in real-time, we see Sulbin, a Bajau fisherman, freediving to 20 metres to catch a fish, all in one breath. That's not all, he can also walk on the sea bed. They should create an action hero based on him.

Oceans: Into the Blue was aired on BBC One and I have no idea if/when will this be screened on our local channels. But I hope it happens soon.

As an air-breathing animal, the human is not built to survive in water. But people have found ways to live an almost aquatic life so they can exploit the sea's riches. From a 'shark-whisperer' in the Pacific to Brazilian fishermen collaborating with dolphins to catch mullet, this journey into the blue reveals astonishing tales of ingenuity and bravery. Daredevil Galician barnacle-collectors defy death on the rocks for a catch worth 200 pounds per kilo. In Indonesia an epic whale-hunt, using traditional hand-made boats and harpoons, brings in a sperm whale. The Bajau 'sea gypsies' of the Sulu Sea spend so much time on water they get 'land sick' when they set foot on the land! We dive 40 metres down to the dangerous world of the Pa-aling fishermen, where dozens of young men, breathing air through a tangled web of pipes attached to a diesel engine, capture thousands of fish in a vast net. We see how surfing has its origins in the ancient beliefs of the ocean-loving Polynesians, and we join a Borneo free-diving spear-fisherman on a breath-taking journey 20 metres down in search of supper.
